Abstract/OtherAbstract:

BACKGROUND: Left ventricular hypertrabeculation/noncompaction (LVHT) is associated with stroke or embolism (S/E). The aim of this study was to assess if the Congestive heart failure, Hypertension, Age >75 years, Diabetes, and Stroke (CHADS(2)) and CHA(2)DS(2)VASc scores are different between LVHT-patients with and without stroke/embolism. METHODS: Records of LVHT patients were retrospectively screened. For stroke classification, the Trial of Org 10172 in Acute Stroke Treatment (TOAST) criteria were applied, for peripheral embolism angiographic findings. Baseline data were compared between patients with and without S/E. RESULTS: In 26 of 169 patients (15%), stroke (n = 24) or peripheric embolism (n = 2) had occurred. S/E etiology was either cardioembolic (n = 18), atherosclerotic (n = 5), or undetermined (n = 3). S/E occurred before (n = 17) and after (n = 9) diagnosis of LVHT/NC. The prevalence of hypertension (62 vs 35%; P < .05), CHADS(2), and CHA(2)DS(2)-VASc scores were higher in patients with than without S/E (2.85 vs 1.26 and 3.69 vs 1.93, respectively; P < .001). CONCLUSIONS: S/E in LVHT is not always cardioembolic, but may also have an atherosclerotic cause. The CHADS(2) score may be useful for clinical decision-making about oral anticoagulation for the prevention of S/E in LVHT patients.
